At this time I am afraid we do not sell any individual components although such a model is always under consideration and may, one day, happen.
But I am unsure what you actually mean by 'certain forum topics to certain place on site pages'. So, without further explanation, I am unable to advise if we even have a component that would allow for what you want.

Hi! Thank you for paying attention to my problem. Well, all I need is to have possibility to place any single topic from the forum on one of my site pages. For instance, I created a profile-page for a person. Then I created a particular topic on the forum for this very person to discuss him. But I need to show this topic not only on the forum but also on this profile-page as an additional information about this person. In BBpress it is made with the help of a certain shortcode. But I only like SimplePress. I suppose this is one of the best in its kind. And I have not found any shortcodes or some other mechanisms of this sort. I suppose it may be a feature available on the payment basis. I`m ready to buy it. This is the only feature I need, so there is no sense in membership. That`s what I meant. I wil be very glad if you give some advice on the problem. If necessary I may post an example here.

I did initially think the template tags plugin would work from reading your initial post, but after your further explanation template tags won't do that. 

Hello! Is there any possibility to buy this particular plugin without buying membership? Work it or not, I will try. Maybe that is what I am looking for.

P.S. It is not my business, of course, but I guess this service (I mean buying single items) is very convenient. I believe there are a lot of people thinking in the same way.

As a customer I prefer to buy plugin to get access to the support forum and aftewards enhance its functionality by buying additional extensions. This works in other cases. Your business model differs a lot. You give users a very responsive forum plugin free of charge and then for many there is no motivation to pay for the service because most people may ve in full satisfied with the core plugin. IMHO.
