Concerns for installation:
1. My website has multiple subwebs and subdirectories. When installing wordpress in root web, is there anything I should be concerned about in regards to the subwebs and other files?
2. I have wordpress installed in a subdirectory, is there anything I should worry about in installing a second blog in the root web?
3. When installing a second blog in same database. In the config file, the line "$table_prefix = 'wp_'; ", is this the actual prefix that needs to be changed?
