Star Trek

Anyone know of any good ones?

There are a lot to choose from.  When I talk to people about joining a fleet, I ask them what they're looking for.  Are they looking for a huge one or small or something in between.  Are they looking for Role Playing or something in particular?  Are they looking for voice communications?  Are they looking to contribute or just be one of the group?

I don't believe in a one size fits all.  Our fleet (Frontier Fleet) is small, but those of us that are active have gotten us to a Tier 3 starbase and a Tier 2 embassy as well as have completed all the special projects.  We have our own forum and voice communications.  Some of our members are even writing a script for an episode.

I think its time for me to join one but aside from when I see people recruiting for one I don't really know enough about what you do in one. 

And what's the deal with random fleet invites? I always decline those.

As Bam-Bam said, it all depends on what you're looking for. 

Some fleets are all about STFs, others are so casual you probably wouldn't even notice that you're in a fleet except the free uniform slot.  Some are pushing 500... but most have 5 or fewer.

Ours (I'm in Frontier with Bam-Bam) is intended to be more of a "Trek simulator" with a fair amount of role-play and respect for Trek canon/history/lore... rather than an "MMO Clan" that's all about looting PvE and collecting kill accolades in PvP.

But... no good plan goes unpunished.  While we were successful briefly, real-life got in the way, and our 50-man fleet of Trek-loving role-players slowly turned into 5 guys trying to make it work with 45 inactive "ghosts".  However, we have been brainstorming on ways to rebuild.
