lsst.community.org is very picky about the kinds of files one can attach to a posting. Would it be possible to eliminate the whitelist and perhaps use a blacklist if concerned about particular file types? (.app and .exe, perhaps?).
Or at least please allow all source code, standard image formats, yaml and json. Here is what I came up with. Some of them may already be allowed and I am probably missing others: .py, .c, .cc, .cpp, .h, .hpp, .yaml, .tex, .csv, .json, .paf, .java, .js, .fits, .jpeg, .png, .txt, .log, .text, .md, .html, .sublime-settings.
