and yes I do have more than 80 forums to exclude (when my forum is ready to go public anyway).
Wow, thats great that Icy will get such a big use
OK, For your database, it depends on your MySQL server as to what you can increase a varchar to. For version > 5.02, you can have varchar 65,535, older versions are limited to 255, but in general you can change varchar to text anyway.
I was going to give you the SQL commands to use, but I'm not quite sure off the top of my head for altering char length, so instead here is a straight forward way to do this in phpmyadmin (use cpanel version rather than the one in Icy phoenix ACP
1) Select the config table from the left frame of phpmyadmmin (you might have to select the DB from a list first).
2) You should be looking at the structure for config table. Observe definition for the config_value row. In the install schema it is created as varchar(255), somewhere along the lines my server seems to automatically turn it into unlimited text. I don't know if this will be the same for you. If there is no limit (no varchar255) then nothing to do. Otherwise:
3) Select the pencil (edit) icon in the config_value row. In the column with "type" - you can change this from varchar to text, then remove the 255 completely from the next column (can be blank).
Then, just edit the maxlength="255" to whatever you want. Actually, I might be wrong but I think maxlength="255" can be removed completely, as there doesn't look like anything in the scripts which checks the length of the field (as usually the browser limits the length of the input string).
