Hi, I like Todd Fillingham's suggestion that that a subscriber sending in a contribution be required to accompany it with a brief abstract, but I would strongly urge you to then submit the abstract and actual article all in the same post. Those of us who are pressed for time will not be able to afford the luxury of going to links for the articles we want to read after reading the abstracts. But it is easy to delete a posting if the abstract points to a topic or content outside one's particular interests. Combining the abstract suggestion with Mark de Vos's very good proposal to have each posting to ppi identified as to type (EDS, SUBS, CHAT, etc.) would go a long way to making ppi a more valuable experience for us and one that readers could handle with less time problems. But would it also be possible to have each posting begin with the letters, ppi, in the Subject Header. Now that postings are coming in with other than Richard Moore shown as the sender, there is no way of knowing it's a ppi post unless the Subject Header identifies it as such. My two cents :) Nick.
