Signature character limit.

Hi permies software mods,
I'm trying to update my signature, but it's now limiting my character limit to 255 - even smaller than it currently is at 448. The forum software is telling me that the character limit for my signature is 766. I'm trying to update it for a signature of only 473 characters but it's not letting me past 255 characters. What am I doing wrong?

New signature that I'm trying to implement:
Worm Bin Design Plans | Permaculture Instruction | BackyardRegeneration.com |  Fungi | Composting | Consulting

Thanks in advance. :-)

I'm pretty sure it allows more when you have pie.  

Found it ...  people with pie get 1000 characters.

Thanks for the reply Paul. I don't mind buying pie to extend my signature character length to 1000 characters.

However, it appears that there might be a software bug either on the frontend reporting of what the signature character limit is (sans pie) or on the backend signature limit itself (sans pie):

My current signature is 448 characters. The attempt to change my signature to 473 characters is being blocked by a real backend (not displayed) limiter of 255 characters when the displayed frontend limiter says the limit is 766 characters.

Is my current signature length of 448 characters a result of being grandfathered back when I had earned pie?

What is the meaning of the displayed frontend 766 character limit and how does that relate to the actual backend 255 character limit?

I'm attaching screen shots.
Thanks again.

ill admit i have noticed this recently. It says i am allowed max limit of 4096 characters. Than it goes on to say no more than two lines.

I appear to not be able to do anything to my current signature. cannot add a space or any character. I can only delete. I found this odd!

looks like some things have been changed. now what is is saying mike? still saying character limit is 766?

devaka did an update.  all sorted now?
