[Zope] Limits on text posting

Hello again, zopistas! Actually, this is not directly related to Zope, but I just wanted to know. I have a simple form with a textarea, exactly, how much text fits in a text area? I mean, is there an upper limit to the number of characters the end user can type in the textarea? -- [ c a r l o s c a r n e r o ] [ r t v c o m e r c i a l ] [ t e x e l @ r t v c . c o m . c u ]
