I too am looking for a new SG to join. I've been playing since early in '06 and was a member of a very active group for several years. However time has taken it's toll on the group and all of the other players have gradually drifted away from the game leaving me very lonely in a big, we;;-stocked base.
I haven't had much luck with recruiting new members so I've decided to strike out and find a new group instead. I thought I had an invite coming from another SG and removed one of my toons (Mr. Mercury) from the old one but the invite never came through and now that toon is stuck being a free agent.
I'm hoping to land on another active group if I can. I don't get to play quite as much as I used to but I'm usually logged in several nights out of any given week. Please send a tell to @Mr. Mercury if you're recruiting, I'd love to hear from you - thanks!
I tend to use the forums here as my task force planning thing or to get in on some unique thing. Or just listen to the Freedom TF Chat channel.
I use SG's for the bases, just to tp around and craft stuff. Nearly all my toons are part of an abandoned marketing experiment from last year. I think there are only two active globals in it, me and Tidbit, so I keep hundreds of millions of salvage & enhancements around.
I have, and recommend all to do this, my own one-member SG that I use as a warehouse for good IOs that I need to keep around. I'm not so big in marketing anymore, but I still have that toon lowball good sets for me.
That said...if you do find a really active and swank SG that's nice, friendly, and helpful, let me know about it. I'll send a toon over. 
If you play villains, just ask in Cap for an invite to Dark Kingdom or Sovereign. We have a mix of east coast, west coast, Australian and Europe players, so there's usually someone on.
There's folks running lv 50 strikeforces everyday and WSTs. Some of our members PL for free.
I'm usually on from 7 pm - midnite pacific time. Just send a tell to Voltez Y or Avsolut Zer0.
Hello Freedom.
I am a returning player of about 6-7 years. I played the game way back when it was first released and gave up once I'd hit 50 and realised there really wasn't a lot of end game content to get my teeth into along with several of my in game friends moving to a game who shall not be named lol.
Anyway since coming back i've been trying to catch up on all the changes and so far i'm not doing too badly, however I really need to find myself an active SG to get into the latter stages of the game.
I've been working ons et bonuses, unlocking my alpha slot, getting various accolades done but of course I always run into a snag later like, the spelunker badge, I need to run BAF's or something for certain salvage etc etc, and tbh, its not as much fun solo.
I have heroes on Union as well as Freedom. I'm hoping to stay on Freedom if I can find an SG.
I have a 50 fire/fire Brute, 50 MA/Regen Scrapper and 32 Rad/MM Blaster so far on Freedom with various level 20's knocking about.
Likely I'll be on my Brute Disco Love Machine, my Scrapper Kim Couture, or my Blaster Intoxify.
If there is anyone out there who can help please get in touch.
Cheers!
