Actually, no - I'd go join a Txevu guild. Yeah - so I did.
But, if I wanted to get a guild up from start, I'd follow Henora's suggestion, mostly. Hats, gloves, wrists, boots, sleeves - OoW Tier 1 Quest stuff, period. Everything I have listed as non-raid gear at
http://samanna.net/sham.gear/nonraider.shtml can be one-grouped by senior Level 70s... or, if your guild isn't that leet yet, two- or three-grouped, provided you can get to the zones. Take a three-group raid of peeps 65+ into MPG and clear your way to one of the four leg-droppers; stay there for a few hours or until the legs rot. Then (or next time) clear in to another one. Repeat. Once you get the hang of it, put your lowest level members in with the big dpsers, have that group out of raid, let them get nice XP (while the rest of the guild helps, but doesn't KS) and they'll get a level or two each by the end of three hours. Level people up and do the same in RS, find a named that's not camped and raid it. Get everyone a wrist and a BP who wants one. By the time you're done, everyone is level 70 and has some AAs, plus nice pants, chest, and wrist. And you've learned how to give and follow raid commands. Off night? Back to getting Tier 1 quest drops and XP.
