Usernames and Allowed fonts

[IrvingvB]

Hey, I got two questions. First one is, how can I let the usernames contain numbers and (capital)letters? In other words, people cannot register their username containing weird signs such was !#%_:.,

Second question is, in the Administration Panel -> vBulletin Options -> User Profile: Style Customizations options under "Allowed fonts", I accidentally deleted all of those fonts. Could someone copy them for me again? I only got "verdana|Verdana, Arial, Helvetica, sans-serif" left. Anyone who has a vBulletin forum has this info that I accidentally deleted, so if anyone could help me, that would be very nice.

1. User registration options->Username Regular Expression -> Enter ^[A-Z0-9 ]+$ that would allow alphanumeric characters including space. Read (?) for more details

2. arial|Arial, Helvetica, sans-serif
times_new_roman|'Times New Roman', Times, serif
courier_new|'Courier New', Courier, monospace
georgia|Georgia, 'Times New Roman', Times, serif
verdana|Verdana, Arial, Helvetica, sans-serif
tahoma|Tahoma, Verdana, Arial, Helvetica, sans-serif
geneva|Geneva, Arial, Helvetica, sans-serif

I might be wrong as I haven't used regex for ages, but the one given will not allow for lower case characters. So I think it should be something like this:

^[A-Za-z0-9 ]+$

Or this if you want to allow . (full stops)

^[A-Za-z0-9. ]+$

Allright, thanks! I have another question concerning this: how can I enable only (capital) letters, numbers and single spaces (so until this you already told how I should do this), but besides these signs, also to allow the specific signs "." "_" and "-", but that these three signs cannot be at the start of an username?

For example:
user-name_ can be used
user_name- can be used
user.name. can be used

but -username-, _username and .username cannot be used.

So to be more specific in what my question is. How do I allow the following signs: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwx yz1234567890.-_

while .-_ cannot be used at the start? And of course, all other signs cannot be used in usernames.
