In this post Make Footnote Numbers Clickable I asked if each footnote number can be made clickable to go to its location in the text. Above, you seem to be explaining how the footnote numbers are made, but it doesn't seem that they're clickable yet. Are they?
If this site can support wikis, have you considered adding a wiki section under "QDL" along with blogs, articles, forums etc?*11594 Wouldn't a wiki take a lot of memory? Isn't your site also limited on how many images can appear on a page without causing problems browsing the page?*11598 Google Images can stack lots of images on a page pretty quickly. What does this site lack for that? Just memory?
If we can select any text as you explained above and then click on Post Reply and the selected text will appear as a quotation in the Reply box and a footnote number is added to the original text (just after the part selected I presume), can you also rig something separately to allow a moderator to label selected text as a premise or conclusion and what number premise or conclusion it supports? It seems like that might then make it possible to collect all of the statements that are premises and conclusions in a separate post, with each premise and conclusion labeled and numbered. Then each critique boxes and refutation boxes could be available for readers to use. How about that?
It's nice that you know your tech stuff and are willing to discuss it. Otherwise, I'd be bored now, I think.
