Too lazy to read other feedback, but here goes what I see
Offers creation:
Each section needs to specify what amount it's looking at (does bandwidth count in TB or in GB? is ram in MB or GB) or allow us to specify via a dropdown for each section -- I filled the entire form and hit submit before it told me it had to be a numeric value, I initially entered "3TB" "1024MB" so on.
Allow a dropdown for currency. I'm sure there's some provider that wants to offer in some currency not USD.
IPv6 -- possible to add an "included" or "ticket required" for IPv6? Maybe it's just me but our VPS don't come with IPv6 by default, but we can do up to 200 individual IPs on our OpenVZ package via ticket request. No solid way to document that in the IPv6 area.
Is there no "Offer submitted" message, or am I blind? I mashed the done button like 4 times before I opened a new tab to see if it was submitted successfully. Edit Location appears to be the same.
Provider Location: Allow the option to link to a Looking Glass if a provider has one. Can be useful for pings, traceroutes, etc.
I love the formatting, especially with a queue system. Will be awesome to know when the post may or may not be listed, LEB is just sort of "if it happens it happens, SURPRISE!!!!" which is frustrating to make sure we have nodes online and ready.
