I find it funny that guy who says he judges people based on sigs has giant annoying text in his, and is now complaining about sigs messing posts up... while still having giant text in his.
It sounds like it's a specific mobile browser issue, unless a bunch of people are affected it may not be worth the effort it would take to troubleshoot and fix it.
Every user here has space for a sig. This sig serves a purpose, right? Most use it to advertise the one thing or the other and yes, it not necessarily serves a good purpose other than drawing attention to the one thing or the other aka diverting attention from the stuff being discussed aka reducing the focus on subjects.
Who is this mr. begging for tips important staff-guy to judge how I use this space when I report a bug? Why can't he think a minute about what the real problem is? Images are already forbidden. Why not forbid color and text size as well and format links with a more discrete underline instead of again color? And why not treat respectful those who take the effort to report bugs?
