I want to use Wall functionality like it in Clubs section of the community. Can I use this control separatelly from Clubs in my project?
well the wall is basically another form of a blog. In a club you have 2 blogs, NewsBlog and MessageBlog. The club wall is re-using the usercontrol from MyPage, so basically you could do something similar in your community modul where you have a blog.
If you don't have a blog like in a club in the module you want to use it, It should be possible to create one and modifyEPiServer.Templates.RelatePlus.UserControls.MyPageUserControls.Wallto work with your new implementation.
Tell us how it goes.
