Some mods i need

[Vinspire]

I've did some search in the forum but this is the error i got 

Code Select Expand

Due to high stress on the server, the search function has been automatically and temporarily disabled. Please try again in a short while.

So, i open a topic to ask about this 2 mods that i've seen before but i don't know which section could i get it.

1. A mod to ask the forummers how did they find out about the site when they are registering themself in the forum.

2. A mod function for them to inform their friends about the forum.

1. You could use my Custom Profile Field Mod to put a drop down box on registration.
2. You can use the send this topic function.
