It really depends on your own playing style aaand on the rules of the guild. Some guilds do not like people to belong to any other guild on any acccount.

I tend to join different guilds on my different gallery accounts that match that gallery's interest. I spend time in each guild in turn as I work on that gallery or am playing with that gallery's pets.

Some people prefer to have all their galleries in the same guild so that it's easier to keep in touch with message boards without having to log into another account.

My main account, ladykirin, where I spend most of my time, is member of a private guild of luffable friends. That's where I'm most active.

On my starry gallery, jedikirin, I'm on the council for a Star Wars themed guild that is *not* very active anymore but which used to be full of SWC friends that actually got me into Neopets. I'm staying for sentimental reasons.

My chocolate gallery, mysticalkirin, is member of the Neoitems guild. I joined because I've been using this wonderful site to support my gallery addiction for quite a while.

I stop by the message boards now and then to keep in touch, but am most active though this forum.

Lastly, my plushie/petpet gallery account, silverkirin, just joined the Plushie Guild, thanks to a gracious invite from one of the forum members here.

Since plushies were my very first collective addiction, I'll probably be somewhat active there.

Oh, all my galleries are also members of the same neocircle, The Galleries Union, but that's a different thing.
