Using the SEARCH functionality, I think a user is more likely to find what they are looking for if the Thread title simple had a brief description of the respective link, but the URL should be inside the post...not a part of the title. For example using RM's recent post:
Thread Title: Basic enclosure design
It's a free download. I've used it and had decent results.
Thread Title: RTAs, SPL meters, and O-scopes
If you guys like that concept...then set them up accordingly, and I will delete the other post/thread references once you tell me you're happy with the system.
