I don't like the thing red link. Also, I like Frances the Mute better than Songs of Innocene. ^^

[edit] DC Meetup notice

Greetings. There is going to be a Washington DC Wikipedia meetup on next Saturday, July 21st at 5pm in DC. Since you are listed in Category:Wikipedians_in_Delaware, I thought I'd invite you to come. I'm sorry about the short notice for the meeting. Hopefully we'll do somewhat better in that regard next time. If you can't come but want to make sure that you are informed of future meetings be sure to list yourself under "but let me know about future events", and if you don't want to get any future direct notices \(like this one\), you can list yourself under "I'm not interested in attending any others either" on the DC meetup page.--Gmaxwell 22:11, 14 July 2007 (UTC)

[edit] Tagalog Wikipedia

Tagalog Wikipedia Campaign March 2008!

Tagalog Wikipedia is campaigning for your participation in writing, editing, assessing and translating articles!
The purpose of this campaign is to expand and improve articles at Tagalog Wikipedia. Your participation will be highly appreciated by the community.

There are over 16,000 articles to view, read, review, edit, and expand, so please visit the Wikipedia Café and the WikiProject Philippines at Tagalog Wikipedia to help out!

The campaign includes seeking your assistance in:

Or just anything you can do to help us just like what you are doing there at the English Wikipedia.

Thank you in advance and regards, Tagalog Wikipedia Community

Finally, Wikipedia is the 7th most visited site in the Philippines. Then why is it that the Tagalog Wikipedia, the Wikipedia in your own language remains unknown to most of the Filipinos? The mission of this campaign is to change that. Will you join us?
