@vj-codes I haven't been assigned any issue yet, can I please take this one?

[God005]

@vj-codes I cam completed my previous task can this be assigned to me?

[vj-codes]

Assigning you @ritvij14
Happy coding!

[ritvij14]

@vj-codes I have a doubt since this is given 2 category tags, will it be counted for both or for one only? For Open Source Hack.

[vj-codes]

This will come under coding @ritvij14
User interface is added as an additional category ,so that it's easy to understand.
UI issues for OSH are mostly redesigning the app

@vj-codes alright. Thanks for the clarification

[ritvij14]

@vj-codes I have just started exploring this project and this is my first issue so I thought I should confirm before sending the PR.
In the Members.kt file, the updateUserList() function uses the getFilteredUsers() function to get a list of users according to the filters in the search query.
In this, I see if-else conditions for checking filters like location and skills, so is this the part where I put a Toast for skills?

Please tell if I am proceeding in the right direction.

yes @ritvij14
