Congrats on the ExtJS Core release! I suggest a specific forum area for ExtJS Core.
In general, ExtJS Core is for content sites and ExtJS Full is for Rich Internet Applications (RIA). For this reason, the usage, target developer base and much of what is discussed are very different. How ExtJS is applied is not the same for a content only site as it is for a RIA. The focus of ExtJS "proper" has been to create VERY nice RIA front ends from the get go. So all us old timer are versed in this practice, all questions are seen in this light and hence the answers geared toward what we know .. the full package.
This is really bad for people that are just interested in usign the Core for a content site.
The new timers coming in to see what this ExtJS Core is all about are hitting comments like "Once you need a xxx - you should be using the full blow product" or "This is just making people program 'wrong' because of 'this or that', they should be building proper RIA apps, etc.
In addition to that point - I have yet to see much focused discussion on the Core and finding them is tough .. becuase the proper package has a core too.
If ExtJS Core is to thrive - it needs JQuery converts and people who are looking to use JQuery for content sites to see how well ExtJS works and want to move over.
When they come to this site and can't find anything good on ExtJS Core and have to filter through lots of posts about stuff they care nothing about - you can imaging the frustration they must feel. Then they find something on core .. and "oh" not the same core ... ug.
I just wanted to bring up the discussion about of having a ExtJS Core forum again now that it is released.
Again Congrats and Thanks ExtJS Team!!!!!!!!!
