This is not the first time someone suggests this. IIRC, this feature will be available in the new forum software that is being developed.
For now, what you can do is go to the
Advanced Search page and do the following:
- Write your name into the "Search for" field;
- Select "most recent topics first" in the "search order" option;
- Check "Show results as messages" (optional).
This will show every post where you got quoted or someone wrote your name.
