Re: [E-devel] GSOC important announcement (final dates)
Also another note: Hello Mentors, Admins, and Students, In anticipation of the end of this year's Google Summer of Code, please make sure that your shirt size and shipping information is up to date in the webapp. We will be printing this year's shirts on American Apparel brand shirts, which are known to run smaller than most brands. Please see their size chart at Men's: http://www.americanapparel.net/sizing/default.asp?chart=mu.shirts Women's: http://www.americanapparel.net/sizing/default.asp?chart=womens.shirts to determine the best size for you. They are cut more fitted than most shirts, so you may prefer to go up a size (especially for women's sizes). If you want to change your shirt size, please update your preference the webapp by Monday August 17, 12 noon PDT / 19:00 UTC. In order to make the delivery of your shirt (and certificate, if applicable) as smooth as possible, please make sure that your address in the webapp adheres to the following guidelines: -Address does NOT contain any commas -Brazilian postal codes contain 8 digits, hyphenated or not (e.g. 13083-030 or 13083030), but must include leading or trailing zeros -Individuals in Brazil, India, and Serbia should make sure their postal code is an international postal code, not a local postal code -Individuals in the US should have their state listed as the two letter abbreviation (CA not California) We hope to have all the shirts and certificates ship in mid-late September, so make sure the address that you list applies to this delivery time. Students, please also double check that your name appears in the webapp as you would like it to appear on your certificate, either in the fields First (given) name and Last (family) name: or Name on documents: The same deadline applies for updating name and address, Monday August 17, 12 noon PDT / 19:00 UTC.
