Check out Startupping, the new
"one-of-a-kind
community resource created for Internet entrepreneurs by Internet
entrepreneurs. It is a place to share information, ask questions, and
tap into the experience of others who have built and are building web
businesses. Read blog posts about startup issues, participate in our discussion forums, and view our wiki resources, including sample term sheets and a glossary."

Other one forum which is new and seem to be fast growing is http://www.bosstalks.com – about project management, althought, it supposes to cover startups/ISVs too.
Have no enough money to buy a building? Don’t worry, because that’s possible to get the business loans to resolve all the problems. Hence take a commercial loan to buy everything you require.
