Adriano, is your point of view and I respect. But, think that there are topics with over 100 pages (for example, some topics on diyaudio.com, even if it does not use IPS software).
When talking about the topic with so many pages at a certain time, suppose, I want to refer to a specific post of a particular user. It's much easier to post the topic page URL than to quote that post user because in case of multi-page discussions, when referring to a previous post, many users want to read that page by seeing or reviewing some reactions of users to that post from particular topic page.
I don't know if you understand, but I have participated in such discussions on many pages and I realize what would be really useful. For this reason, I considered it necessary to make that observation regarding that plugin.
That link shares user posting but that's not what I wanted! I would like that after applying Adriano Faria's plugin, I can easily find a page of the topic where a certain user made a certain post. In fact, in my previous post I think I was as clear as possible!
