+
+Από τη συζήτηση [url=https://www.thmmy.gr/smf/index.php?topic=67629.0]εδώ[/url], ξεκίνησε ένα project με στόχο τη δημιουργία εφαρμογής για Android κινητά που θα συγκεντρώνει και θα κάνει πιο εύκολη τη πρόσβαση σε μερικές από τις βασικές σελίδες και υπηρεσίες που αφορούν τη σχολή και χρησιμοποιούμε καθημερινά.
+
+Μετά από 2+ μήνες δουλειάς και πάνω από 9000 γραμμές κώδικα [size=9pt](.java, .xml και άλλα)[/size], σήμερα ανεβάσαμε για πρώτη φορά την εφαρμογή (σε closed alpha phase) στο Google Play Store!
+
+Προς το παρόν η εφαρμογή υποστηρίζει κάποιες από τις βασικές λειτουργίες του forum. Σταδιακά θα ενσωματώνονται όλο και περισσότερες λειτουργίες, για παράδειγμα ενός συστήματος ειδοποιήσεων για νέες ανακοινώσεις του ethmmy και της σελίδας της γραμματείας, instant chat κ.ά., ανάλογα πάντα με τις ιδέες, τη διάθεση και την ενέργεια όσων θα συμμετέχουν.
+
+Αυτή τη στιγμή με το project ασχολούμαστε εγώ και ο L, ενώ έχουν βοηθήσει ο iason1907 και ο [url=https://www.thmmy.gr/smf/index.php?topic=67565.msg1163192#msg1163192]nohponex[/url].

+
+Αν ενδιαφέρεσαι κι ΕΣΥ να ασχοληθείς με το project μπορείς να το κάνεις με πολλούς τρόπους:
+[list]
+[li]Αν ξέρεις προγραμματισμό μπορείς αρχικά να ζητήσεις πρόσβαση στο repository. Χρειάζονται [i]άμεσα[/i] νέοι developers για υλοποιήση καινούργιων χαρακτηριστικών,  διόρθωση εντόμων,  σύνταξη των javadocs και του documentation γενικότερα, white-box testing, υλοποίηση του backend στο server που στήθηκε πρόσφατα και πολλών άλλων. Αυτό, αρχικά, θα γίνεται με forks και merge requests - και πάντα στο ρυθμό που μπορείς να συνεισφέρεις.
+[/li]
+[li]
+Να αναφέρεις bugs, να προτείνεις βελτιώσεις και να συμμετέχεις σε συζητήσεις, είτε στον [url=https://discord.gg/PVRVjth]Discord server[/url], είτε αποκτώντας πρόσβαση στον Issue Tracker μας.
+[/li]
+[li]
+Να κατεβάσεις και να δοκιμάσεις την alpha έκδοση της εφαρμογής από [url=https://play.google.com/apps/testing/gr.thmmy.mthmmy]εδώ[/url] αφού πρώτα μας δώσεις ένα gmail για να αποκτήσεις πρόσβαση.
+[/li]
+[li]
+Να έρθεις σε άμεση επικοινωνία με την ομάδα μέσω του Discord ή στέλνοντας email στο thmmynolife@gmail.com.
