Delete forum account

seilogramp I have no button for "delete account" in my profile / settings.

And I have also send a PM to Garmin-Blake, but no respond. 

Then you'll need to contact Garmin directly - https://support.garmin.com

It's possible your forum account is tied to your Garmin account and deleting it could have adverse consequences.

Okay thanks seilogramp
I have already contacted Garmin Support, but they told me they could only help with product support. For deleting the forum account I should ask the question here on the forum, they said. Developers on the forum should solve it. 
The Garmin Connect account and Garmin Forum account are created separetly, so delete one of them should be possible.  

Yes thank you. I also send a PM to Garmin-Blake earlier this weak.
