UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support I need to add more groups

As the last resort you can change the field type to TEXT. That will allow you a great deal of groups to be stored but it will come at a price. You will need to change the index to that field to a FULLTEXT one and then modify the .threads code in every area that this field is queried to comply with the FullText searches of MySQL. It is quite a task but if you must, I see no other alternative.
