The guys from Tech Radar compiled a list with 40 brilliant Gmail hints, hacks and secrets. If you are not using Gmail yet, well, you are with the minority. Here are the first 3 items on the list:
1. If you haven’t already created a Gmail account, you no longer need an invitation to do so. Just go to www.gmail.com and click Sign up for Google Mail.
2. Gmail blocks most executable filetypes as a virus protection measure. If you absolutely have to send EXE or DLL files to a colleague, use something like DropSend. You can send up to five files per month for free.
3. Attachments sent in formats that Google Documents can read can be opened direct in your browser. That list includes Word, Excel, PowerPoint, PDF, and RTF files.
