I'm an emissary in UWF. We guild all types - new players and vets. We offer nightly hunts and a host of unofficial events throughout the day. On our forums, we have lots of power training tips and such. We're an adult guild and, whenever possible, we try to heighten the fun and lessen the drama.
We don't drop books or runes or anything. We have one member, animal, who recruits in New Haven a lot. Otherwise, people typically approach us. I've never directly asked someone if they wanted to join and I'd say I guild maybe 3-4 new members every week.
Yet, truthfully, as has been stated previously, numbers don't mean much. Plus, our membership ebbs and flows, just like in any other guild. If people like us, they stay; if they don't, they go.
Not saying we're the best there is, either. As a PvM guild, we're obviously not everyone's cup of tea. Also, some people like a smaller, tighter-knit community. There is room for all types on Atlantic.
Personally, I like it because I have friends there.
As far as us being trammies, I'd say that's a fair blanket statement, insofar as blanket statements are fair. Though, I think our members with alts in HOT, HEAT, LNR, and COL would take offense.
As for why we've grown...I think it has to do with our flexibility. Unlike LLTS, we don't require that people guild all of their toons. Our members can be in any guild that want to be in. Moreover, no meeting or hunt is mandatory. We realize that people are paying to play a game - we try not to interfere with this dynamic. Finally, as an adult guild, we only have three basic rules: 1) Don't PK guildies, 2) Don't steal from guildies, and 3) Don't cuss in guild chat. Easy to join, helpful members, flexible rules, lots of hunts...I 'spose that's how we've ended up growing so large.
