It will be done to a Min, but be patent with it.
Some things you may notice:
Website will not display,
Randomly being taken to the Blog, or the Blog taking you here.
Logging in being redirected and forced to another place.
Random Errors on the site.
Ignore them, and when am aware the site is being effected in this way,
I will revert back and retry.
What is one doing

A merge of 6 Different PLugins fro for Wordpress and the forum.
The Idea, is i want a Single post from Wordpress to be posted into the forum (Under News)
I then want comments to work Back and forth, If i post on the blog it posts here on the forum, If i post on the forum it goes back to the Blog.
So i will have to merge the Users or get them to share usages.
Things may go smooth, but if they dont thats why
