Guild Wars 2

I created a signature earlier and then decided to add an additional link to include my GW2 guild.

I noticed that the signature in my posts didn’t seem to change after I moved some content out of link text. I assumed that there was something in my signature that wasn’t allowed, edited it back down to short links without descriptions, and then spotted that my signature was now showing the full previous version (with descriptions). So I reverted back.

I was wondering, is the delay down to a background process of authenticating signature changes? or just a replication delay between changing a profile and it updating on the forum?
