I've not looked at your plugins but are they not written using the standard plugin installer style ?
They are.
There should be no dependancy on table prefix name. I have sites with gl_ or nothing as a prefix. It's possible to have multiple GL installations in the same database all using different table prefixes.
There is no dependancy on the name except for while they are still in development after dev the sql calls get the ".$_DB_table_prefix." call added.
The plugin name is just that a name or markerting name. It also often (most cases) the name the plugin internally is called and referenced by the Plugin API functions and GL plugin related directories.
Yes but I just wanted to be sure, I *HATE* steping on peoples toes even by accident.
