footer text
 

how do i edit footer text?
and how about the text i want to appear with every post?

Which footer text are you referring to? The lower footer in the forum? If so there are two possible ways to do that depending upon what you want to put there. If you want to add your own copyright then you can do that by going to Settings > Options > Copyright Text.

If you want to change your disclaimer then that might be a template edit, so you would need to find that in the template and change it there. More and likely its in the footer template so you would need to go to Styles & Templates > Style Manager > Choose the style you are using and on the far right click the drop down and choose "Edit Templates". Find the footer template, open it and edit from there.....BUT I caution you. If you do not know HTML I suggest that you do not try and edit the template on your own you can screw up the site by editing a template incorrectly. If you are unsure post your footer template here and use the "Code" tags to post the code and one of us can probably help you edit it.
