I am not receiving MakeUseOf Geeky Fun emails.
I subscribed but nothing?
If you have changed youre email addressthen you need resubscribe to Geeky Fun feed again. Here is the link to email subscription, http://feedburner.google.com/fb/a/mailverify?uri=GeekyFun
What do you mean you changed your email address?
Are you using a different email address and are you no longer receiving the subscription since then? If that is the case, did you try to sign up again with your new email address?
i was also receiving it
but then i changed my email address
I'm not absolutely sure, but I don't think the subscription includes Geeky Fun updates. I think it only includes Best Sites & Programs, Give Away's/Deals and Answers, or at least that's all that I'm getting. Make sure they are not going to your Junk or Spam folder.
actually at first i was receiving them
I am subscribed to Geeky Fun via email and I'm still receiving the emails. Did you check your spam folder?
