Signature banner question

[gcaldani]

Here is the first simple question:

will they be available once we become subscribed players (so, from 18th of may)?

Actually, it's already long time i removed other mmo info from my signatures leaving only Ryzom mentioned, so I want to use the banner as soon as possible.

Another question, maybe less simple:

some site restrict the signature banners to 400 px width (allowing higher width only for people subcribed to their services, for a fee).
I've seen that the actual banner is 500px width.
There will be any way to have different widths for it (at least 400px)? Otherwise I already know i will not be able to use it on some forum.
