Five Things To Do This Weekend

No money? No problem! Here’s five ideas from the last week on Lifehacker that won’t cost you a cent:

• Use Namechk to secure your favourite user names
• Backup your email and browser profile with MailBrowserBackup
• Learn another language with free online lessons
• Make sure your frequent flyer points transfers are set up properly
• Theme your copy of Firefox with GetPersonas.com
