Hello.  I'd like to know if any of the Zoho Creator developers out there are using Zoho Creator with other Zoho Apps and how well they interface together in allowing bi-directional communication (whenever possible).

My interest in this is due to that fact that I don't want to reinvent the "wheel" so to speak if a Zoho App already provides the functional capabilities.

For example, I have functional specs from a client that requires a Web Application where the majority of it's functional requirements can be built on Creator, but they also require a Forum (which I thought about using Zoho Forums) and the ability to generate Invoices (Zoho Invoices) for specific users.  I'd like to be able to combine the use of both Forum and Invoices within my Zoho Creator App and allow the chatting function of Zoho Chat to allow IM within my program.

I'm thinking of using Zoho Creator HTML views to accomplish this by referencing either Widgets or permalinks but is there an easier and better way? Also, can you provide any experiences and limitations that you have combining Zoho Applications together.  I've done this using Zoho Reports & Creator, but wanted to know if any of you have done other applications.

Thanks.
