The whole set of these plugins are great! However, I needed to manually edit them in order to have them blend in with my site, and that's not ideal.
The specific problem is that you assign "text-align:center" to the "newsociallogins" element directly, and then again to the "OR" item that's inserted beneath them. Obviously, not all themes will want that style applied to those elements.
In a future version, can you move those style declarations to a CSS file and also make sure that the "OR" element is selectable directly using a class of its own? That'll just let us restyle them without worrying about our changes getting trashed by a plugin update.
(And really -- these are fantastic plugins. Good work!)
