Wikipedia Links v1.0 [CB]

[ⓦ৹₪deⓡ]

This code will add a new UBBC button () which will allow your users to add a link to a Wikipedia article. The syntax follows Wikipedia's link syntax.
Examples:
[[Wikipedia]] => Wikipedia
[[Wikipedia|Free Online Encyclopedia]] => Free Online Encyclopedia

The new tag will work in PMs and Posts. Do NOT PM me for support or requests, that's what the coding boards are for. Edit where indicated.
Enjoy,
~Wonder
