There is currently a filesize limit of 19.5 KB for text files.

All the other file size limits are way higher and I don't really see a reason for such a small filesize limit. Could we have this limit increased to perhaps 100 or 150 KB?

This would give us a chance to attach files like dxdiag reports and the like directly without zipping or converting them. While for many players it might not be a big deal to zip a file, especially for those without a lot of technical experience it might help a lot, when it comes down to things like bug reports and technical problems, the easier it is the better.
