[quote=madskills435]5.How do i search for specific role plays?[/quote]
Search function, alas, has yet to be implemented. It is either a Work In Progress or on the list of things to be done, though. So to find specific RPs, you either have to dig through the forums, or dig through recent user posts. You might try using google to search, but not 100% sure on parameters to use there.
[quote=madskills435]6. How do i link people to role plays?[/quote]
open roleplay you want to link.
Select the URL. Copy it.
paste it into this thing, right after the equals sign:
[url=]link to the RP[/url]
or if you just want an url without descriptive text on the link, just paste it into this:
[url=]
