I've just got my self an Android tablet.
The links in Geekzone emails don't work in some email clients. The OEM email client is one of the affected clients as is Outlook for Android.
Another website I use that sends notification emails like Geekzone has the same problem. The links are displayed in a turquoise colour rather than the normal blue colour. Other email clients like Blue Mail and Cloud Magic work OK.
Is this an issue caused by how the websites send the links or a problem with the email client?
