Kindle Fire Issues

When I try to post on a sports forum, I can enter the subject, but I cannot post to the body of the message. What am I doing wrong? Anyone else having this issue?

Are you able to post to the same forum using a “normal” computer and web browser? Are you using Fire with fat fingers or are you using a stylus?

FWIW, I have a Kindle Fire and actually posted to the SDMB with no problems.
