For the Events page, I have a couple suggestions:

1. I think it would be good to change the title to something like "ONNX Runtime at Microsoft Ignite Conference" and then making the blurb more focused on the ORT content that will be covered (instead of using the description from Ignite as a whole).
2. To that same effect, change the button from "Event Page" to "Microsoft Ignite Page".
3. For me, the image for the Ignite section is showing up as the same image used for the ONNX Community Meetup:
   
   I think it would be good to use another image.

For the Models page, I think it would be good to have more specific distinctions between each of the categories, particularly the ones on Hugging Face. Right now, it's not really coming across why someone would use one vs. another / what the difference is.

Also, this is super nit-picky, but Hugging Face has a space in it (not HuggingFace).

For example:

1. ONNX Community (hosted on Hugging Face): Access, share, and discuss ONNX models published to Hugging Face by members of the ONNX Community.
2. ONNX Model Zoo (hosted on ONNX website): Explore pre-trained ONNX models curated by the ONNX community.
3. Qualcomm ONNX Models (hosted on Hugging Face): Discover ONNX-compatible models optimized for Qualcomm hardware on Hugging Face.
   Then you can add a line after these 3 sections to the effect of "Access all ONNX models available on the Hugging Face Model Hub here." (The ONNX Model Zoo does the same: https://onnx.ai/models/.)
