Bankroll management

[chucklhead]

Howdy,
I have been transferring my bankroll from site to site, taking advantage of some of the bonuses. Is there any reason to keep some money in all my accounts, or is it better to end up with one larger bankroll at one site (say Party Poker). For example, I just earned my bonus at The Poker Club. They have a paucity of players though, and often have only 1 or 2 tables going. However, I found the games, especially the 5 player sit-n-goes, very soft. Is there an advantage to keeping some money at The Poker Club? Is there any danger of a site like this folding up and taking my money?

Any thoughts on internet bankroll management would be appreciated.

Thanks,
