I noticed a few small corrections I would make on the portal page:
- delete the brackets around the Mumbai University link at the very top. (The link is external, so only one bracket is needed on either end)
- Revise the external link to Pinboard so that the work "Pinboard" is the link, rather than having the following  as the link.
- add in the last two images in the gallery
I can see that the wiki code is a big mix of things. I wonder if it would be better in the long run if the portal page followed a more structured approach. There are many institutional portals which began using the instructions at Create_an_institutional_OER_portal_page. The page would start with a navigator, including the two images at the top, and the text, and would follow with a number of editable boxes showing the various content. Each of the boxes displays content from a subpage, which is accessed via the edit button. The advantage of this method is that it's easy(er) for those that follow to figure out how to update the portal. Here's the category of institutional OER portals if you want to check out this approach.
Also, I suggest adding your portal page to the Institutional portals category. Add the code [[Category:Institutional OER portal]] at the very bottom of the wiki text. I also suggest adding the page to the India category.
Let me know if you have questions about any of this.
