I ran a local Star Trek club here (Red Deer, Alberta) in the late '80s to mid-'90s.
We had our club organized like a ship, and since most of us were also in the local SCA, we were used to roleplaying. So we all created one or two personas of ship's crew who could have been part of Starfleet, and ended up taking some of it right into parody and satire.
Our club newsletter/fanzine was called Thataway! and included minutes of the meetings, plans for conventions, some fanfic, word puzzles, I wrote a serious astronomy article each issue (for those of us into astronomy; we had a few stargazing nights here and there), and whatever else we could think of. We tended to emphasize the humorous side of Star Trek (to this day I cannot write a serious Star Trek story; it always veers off into parody/satire as though it has a mind of its own).
A friend and I wrote a soap opera parody of TNG, chronicling the adventures of the U.S.S. Surprise!, with Captain Jacquard and his Third Officer Bill Biker (don't ask what happened to the First and Second Officers; it was messy and we don't talk about it), Bill Biker's girlfriend Helanna of Troi, Dr. Smasher and her son Eastley, the rest of the bridge crew, plus Transporter Chief Kilometres O'Brien (Canadian group, remember; we speak metric here).
There were two regional science fiction conventions happening in Alberta back then - one in July and the other on Thanksgiving weekend (October). Of course we decided to make ourselves uniforms, and since this was before "Yesterday's Enterprise" aired, nobody could tell us that our design that was a mix of TOS series/movies and TNG was wrong. It got interesting at the fabric store when we tried to explain to the salesclerk why we refused to buy anything in red - "because people wearing red get killed" (guess she'd never heard of Star Trek and thought we were BSing her).
We also had an annual barbecue every August, and I'd put on my "Alexius Trebekius" persona and run a game of Star Trek Jeopardy!. The score was in points instead of dollars, of course, and I'd assemble a selection of prizes that I bought in the dealers' room the previous month at the convention. Everyone got a prize, and got to choose in order of how many points they had. It was nice to see the winner's eyes light up one year when he saw that I'd scored an autographed copy of one of Peter David's books. He was the author Guest of Honor that year at the convention, so I bought two books - one for me and one as a prize and got him to sign both of them.
Some of the antics we got up to at conventions... the guy who was our Captain was also the ship's Assistant Tribble Keeper (we don't like to think about what happened to the Chief Tribble Keeper; it was another messy situation), and one year we decided to play a prank on him. A couple of us took a weekend and hand-sewed a few dozen tribbles, some in some very bright colors, and arranged with the rest of the club members who were going to the convention, plus some SCA friends who weren't in the club but were willing to go along with the joke, to hand him tribbles whenever they saw him - passing in the hallway, attending panels, going to room parties... pretty soon he couldn't go anywhere without being given a tribble. And then someone put the blue one in the drinks cooler, where the poor thing got quite chilly...
This was all 30 years ago, and of course the group didn't stay together all this time. Some moved away, or went off to college, I ended up concentrating more on my SCA activities (ended up wearing a few more hats in that group than intended, and they involved a lot of mundane paperwork), and then a couple of us got involved with starting a science fiction club at the local college. We ended up playing a lot of D&D and having themed parties, like a Hitchhiker's Guide to the Galaxy party where we watched my VHS tapes of the TV series, fish-themed junk food was on the menu and everyone had to come in their bathrobes, and also a Dragonlance-themed Christmas party (there's a section in The Inn of the Last Home sourcebook with recipes for appetizers, entrees, and desserts, plus alcoholic and non-alcoholic beverages).
So the '80s and '90s were full of Star Trek, science fiction, and RPG activities. We also put out a smallish book of filksongs, and I still add to that now and then (someone suggested I should add more verses to a couple of them, and I guess 30+ years later is better than never, so I started on that earlier this year).
