Assume I have opened the webpage
How can I search for all tickets which I have opened I the past (which maybe closed meanwhile)?
Without knowing keywords they contain.
I want to use just my account login name
I actually don't know, would need to check this.
We didn't write the tracker, it's Sourceforge who is resposible for this.
In fact we are migrating to a different bug tracking system, as we find it very time consuming and hard to use. Something more professional, coming soon!
You can try https://sourceforge.net/auth/subscriptions/
It lists all "tools" (obviously this means tickets and discussion threads) you have an email subscription for, which by default is the case when creating a new ticket.
However, I am not sure whether it will give you everything, the Sourceforge ticketing system is not always fully consistent.
