Resource types

I have been operating under the assumption that the limit for things that are directly stored in the database is 64K (this is a database limitation, not Moodle). A webpage resource would fall under this limitation, and probably the assignment description or forum entry as well. So if I have anything very complicated, I generally upload it as a file and then link to it.

Are your people trying to link to a file, or enter the information with the moodle html editor?
