So, I was looking at the database to see what's the maximum size a post can be and I see that it's a text field. And I dash off to MySQL.com to read up on column types and their max sizes:
Text, 64 KB
Mediumtext, 16 MB
Longtext, 4 GB
Would it mess up WP in any way if I upped the post_content field to mediumtext or longtext?
