I'm not one of the official admins, just an established Strolenati, just saying that up front so you can take what I say accordingly (i.e. with a pinch of salt *wink*). So it's my understanding that Chrome tends to work better with the Citadel than IE although personally I'm an IE user and it tends to work fine for me with occasional hiccups.
As to workaround around your submission problem, https://strolen.com/ideas/view
, there is a link Write An idea on the right hand side if you scroll down a little. Try that to see if it works for you. If it doesn't, then it's a problem for Strolen and/or Val (they are the actual admins, there are more admins but they are the main ones for functions on the front page) to take.
