Hi Plantrob, and welcome!
I think that Dave, who built, maintains and administers this site usually reads all posts in this forum, so he'll see it. My guess is that you would be linking mostly to "Parent Plant Pages" in the Plant Database, or specific articles.
Would you want to display links pointing to specific ATP discussion forums, like Daylilies or Orchids? If I had an esoteric question and didn't know which Goggle hits to trust, I would go to one of those forums, search briefly, and then post a question.
I like your idea of collecting "good" links.
I used to be more of a seed trader, but a few years in the Hog Wild Piggy Swap has left me with more seeds than I have room or time to plant. Have you seen the HWPS? It's as much an annual party and year-long chat thread as a seed-swap. Cubits, Ella's Garden, Cottage Gardening forum for the Chat thread:

Last year's Have and Ask Lists are here:
http://cubits.org/ellasgarden/...
It's a many-to-many swap where people list their currently available seeds, and then others ask for specific packets. When that is over, and dozens of people have asked for 100 or more seed varieties each, we bundle up and send the requested seeds to Ella. She re-packages them and sens them back to us. That really minimizes postage!
But it is a once-per-year event.
