• I Modified the Nominations component to conditionally render a message indicating that nominations are currently closed.

Generally good, but should address my feedback before merging.

Will do the changes but, I see you have used head tag but, head is not imported in the code. I will do a Pr fixing that

Thanks, nice catch

Looks good to me, I'll wait for @lhvy before merging though

Was considering utilising inline conditional rendering (e.g. ternary) to avoid repeated code like the head/title, and the fluff around the h1, but it ended up being too convoluted. I think how it is currently is the best solution, apart from a complete rewrite abstracting sections into different components like NomineeSection and NominationInfo.

Meant to request @lhvy rather than re-request review from myself, oops

Looks good to me. Remember to add Resolves #xx to your PR description so the associated issue will close automatically.
